This PR fixes uploads the `edit_events` table.
We were trying to insert into a column that didn't exist:
```
HTTP error 500 Internal Server Error: failed to upload to table 'edit_events'
Caused by:
bad response: Code: 16. DB::Exception: No such column os_name in table default.edit_events
```
Release Notes:
- N/A
This PR adds a REST API to the collab server for searching and
downloading extensions. Previously, we had implemented this API in
zed.dev directly, but this implementation is better, because we use the
collab database to store the download counts for extensions.
Release Notes:
- N/A
